1.1 SAFETY PRECAUTIONS

NOTICE : Comply with all cautions and safety related notes

located on or inside the cabinet and on the chassis or

picture tube.

The following precautions should be observed :

1. Do not install, remove, or handle the picture tube in any manner

unless shatterproof goggles are worn.

People not so equipped should be kept away while picture tubes

are handled.

Keep picture tube away from the while handling.

2. When service is required, even though the HDTV PROJECTION

MONITOR an isolation transformer should be inserted between

power line and the set in safety before any service is performed.

3. When replacing a chassis in the set, all the protective devices

must be put back in place, such as barriers, nonmetallic knobs,

adjustment and compartment covershields, isolation resistor-

capacitor, etc.

4. When service is required, observe the original lead dress. Extra

precaution should be taken to assure correct lead dress in the

high voltage circuitry area.

5. Always use the manufacture's replacement components.

Especially critical components as indicated on the circuit

diagram should not be replaced by other manufacture's.

Furthermore where a short circuit has occurred, replace those

components that indicate evidence of overheating.

6. Before returning a serviced set to the customer, the service

technician must thoroughly test the unit to be certain that it is

completely safe to operate without danger of electrical shock,

and be sure that no protective device built into the set by the

manufacture has become defective, or inadvertently defeated

during servicing.

Therefore, the following checks should be performed for the

continued protection of the customer and service technician.

Leakage Current Cold Check

With the AC plug removed from the 120V AC 60Hz source, place

a jumper across the two plug prongs. Turn the AC power switch

on. Using an insulation tester (DC 500V), connect one lead to the

jumpered AC plug and touch the other lead to each exposed metal

part (input/output terminals, screwheads, metal overlays, control

shafts, etc.), particularly any exposed metal part having a return

path to the chassis should have a minimum resistor reading of

0.3M

and a maximum resistor reading of 5M. Any resistor value

below or above this range indicates an abnormality which requires

corrective action. Exposed metal parts not having a return path to

the chassis will indicate an open circuit.

SD-533HD5, SD-643HD5

Leakage Current Hot Check

Plug the AC line cord directly into a 120V AC 60Hz outlet (do not

use an isolation transformer for this check). Turn the AC power

switch on.

Using a "Leakage Current Tester (Simpson Model 229 equivalent)",

measure for current from all exposed metal parts of the cabinet (input/

output terminals, screwheads, metal overlays, control shaft, etc.),

particularly any exposed metal part having a return path to the

chassis, to a known earth ground (water pipe, conduit, etc.). Any

current measured must not exceed 0.5mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITS

OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL

SHOCK HAZARD AND MUST BE CORRECTED BEFORE

RETURNING THE SET TO THE CUSTOMER.

High Voltage

This set is provided with a X-ray protection for clearly indicating

that voltage has increased in excess of a predetermined value.

Comply with all notes described in this Service Manual regarding

this hold down circuit when servicing, so that this X-ray protection

may correctly be operated.

Serviceman Warning

In the status of the black picture (video muting is being applied)

when no signal is input, high voltage of this set during operation is

less than 30.5kV. In case any component having some relation to

the high voltage is replaced, confirm that the high voltage is lower

than 30.5kV in the status of the black picture when no signal is

input.

To measure H. V. use a high impedance H. V. meter.

Connect () to earth and (+) to the FBT anode cable connector. (Refer

to section "7.1.2 DISASSEMBLY".)

X-radiation

TUBE : The primary source of X-radiation in this set is the picture

tube.

For continued X-radiation protection, the replacement tube must be

the same type as the original, PIONEER approved type.

The picture tube (CRT Service Assy R, G, B) used in this set holds

complete guarantee against X-ray radiation when the X-ray is sealed

(See page 4). Accordingly, when the current in flowing to the picture

tube (CRT Service Assy R, G, B), be sure to perform it by putting

the tube into X-ray sealed applied state. Avoid absolutely to flow

the current to the picture tube (CRT Service Assy R, G, B) itself.

Moreover, when the voltage of the high voltage circuit becomes

abnormally a little higher, the picture tube radiates X-rays.

Accordingly, when servicing the high voltage circuit be sure to

replace as an assy with the POWER SUPPLY Assy in the manner

in which has been adjusted to perform normal operation.

1.2 PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in PIONEER set have special

safety related characteristics. These are often not evident from visual

inspection nor the protection afforded by them necessarily can be

obtained by using replacement components rated for higher voltage,

wattage, etc. Replacement parts which have these special safety

characteristics are identified in this Service Manual.

Electrical components having such features are identified by marking

with a

on the schematics and on the parts list in this Service

Manual.

The use of a substitute replacement component which dose not have

the same safety characteristics as the PIONEER recommended

replacement one, shown in the parts list in this Service Manual,

may create shock, fire, X-radiation, or other hazards.

Product Safety is continuously under review and new instructions

are issued from time to time. For the latest information, always

consult the current PIONEER Service Manual. A subscription to,

or additional copies of, PIONEER Service Manual may be obtained

at a nominal charge from PIONEER.

1.3 CHARGED SECTION, HIGH VOLTAGE GENERATING POINT AND X-RAY

PROTECTION

Charged section

The circuit in which the commercial AC power is used as it is

without passing through the power supply transformer.

If the charged section is touched, there is a risk of electric shock.

In addition, the measuring equipment can be damaged if it is

connected to the GND of the charged section and the GND of the

non-charged section while connecting the set directly to the

commercial AC power supply, In this case, be sure to connect the

set via an insulated transformer and supply the current.

X-ray protection

· Regarding the parts which are relative to radiation of X-rays (There

is the danger to radiate X-ray from the individual CRT Service

Assy R, G, B), there are notifications of caution in the individual

schematic diagrams. Be sure to read them for safety's sake.

· The component parts for X-ray protection are as follows:

When the current flows to the CRT Service Assy R, G, B, be sure

to perform it with these parts being attached.

Protection from the X-ray radiation is maintained in the state in

which these parts have been installed to the CRT Service Assy R,

G, B. Accordingly, never supply current only to the CRT Service

Assy R, G, B.

Moreover, the anode voltage of the CRT Service Assy R, G, B

should always be kept not higher than the predetermined value (in

the minimum brightness and picture state when non signal input

is less than 30.5kV). Be sure to drive the CRT Service Assy R, G,

B by using a completely functional Deflection Service Assy

(including FBT) which have been adjusted completely in the

combined state. (When the voltage abnormally becomes high, the

X-ray protection circuit will operate.)
